The Male Prest-O-Lite Soft Nose x 1/4 Hose Barb Brass Wheel is a gas fitting designed to connect a Prest-O-Lite (POL) tank valve to a flexible hose for acetylene or propane applications. The soft nose POL connection provides a secure, leak-proof seal without requiring a wrench, while the hose barb ensures a tight grip on the gas hose for reliable fuel delivery. The brass wheel allows for easy, tool-free hand-tightening, making it ideal for use in oxy-fuel torches, welding, brazing, heating applications, RV propane systems, and portable gas equipment.
